What Mobile Broadband Network Ltd does

Mobile Broadband Network Limited (MBNL) is a UK private limited company jointly owned by EE (part of BT Group) and Three UK (part of VodafoneThree Holdings Limited), established in 2007 as the telecommunications industry's first network-sharing joint venture. The company manages a shared mobile network infrastructure estate of approximately 18,000 Radio Access Network (RAN) sites that collectively carry roughly 75% of UK mobile data traffic, serving the tens of millions of customers of its two shareholder operators. Its core technology platform is Hardy OSS (Operations Support Systems), launched in 2024, which provides asset tracking, maintenance workflow management, and operational visibility across the shared estate, layered on top of a 2G/3G/4G/5G shared network architecture.

MBNL's product portfolio spans the full lifecycle of telecom infrastructure: shared RAN infrastructure management, transmission estate management, site surveys (rooftop and ground-level), site-provider relationship and lease management, energy bureau operations covering approximately £200m of annual energy spend (including billing assurance, tariff optimisation, and sustainability reporting under SECR, ESOS and Net Zero frameworks), building safety and compliance (Building Safety Act 2022, CDM, fire safety), inspection and maintenance (I&M), infrastructure intelligence (KPIs, KRIs, dashboards), and community relations. The company employs roughly half a dozen senior leaders (Managing Director Gervase King plus Directors of Finance & Energy, Infrastructure & Estates, Legal/Governance/Operational Excellence, Commercial/IT/Digital Enablement, and Operational Services) and is headquartered in Reading, UK, having moved from Amersham in 2018.

Revenue is generated exclusively through managed-services contracts with its two shareholders under a private joint venture agreement; pricing is not publicly disclosed and the company does not pursue external customers. MBNL is currently mid-pivot: launched in 2024, a five-year strategic roadmap formalises its transformation from a passive network-sharing entity into a proactive Infrastructure Management Services provider, with active transformation programmes for Inspection & Maintenance and Notice to Quit underway in 2025. The shareholder base expanded materially in 2025 with the merger of Vodafone UK and Three UK into VodafoneThree Holdings, which has committed £11bn to UK 5G expansion, directly enlarging MBNL's addressable network build and management scope.

Broad incumbents

• American Tower Corporation: Global tower and digital infrastructure REIT with ~220,000 communications sites. Comparable as a large-scale mobile infrastructure provider, though primarily an asset owner rather than a JV-based service manager.
• SBA Communications: Global tower operator with ~40,000 sites across the Americas, Africa, and Asia-Pacific. Comparable as a major mobile infrastructure owner; less service-led than MBNL but plays an adjacent role in the value chain.
• Cellnex Telecom: Europe's largest independent tower operator with ~112,000 sites across multiple countries. Comparable as a major mobile infrastructure platform, though Cellnex owns and leases sites while MBNL manages them on behalf of shareholder operators.
• Helios Towers: Tower company operating across Africa and selected European markets with a shared-infrastructure commercial model. Comparable to MBNL's operator-focused, multi-tenant approach to mobile infrastructure.
• Crown Castle: US tower and fiber infrastructure provider with ~40,000 tower sites plus fiber. Comparable as a major mobile infrastructure operator with both site ownership and adjacent service overlay, but operates in the US market.

Regional players

• Arqiva: UK-based broadcast and mobile infrastructure provider operating towers, sites, and broadcast networks. Comparable as a UK-only infrastructure operator serving telecom and media customers with shared site assets.
• Deutsche Funkturm: Deutsche Telekom's tower and site infrastructure subsidiary in Germany. Comparable as a telecom-owned mobile infrastructure entity, although it operates under a parent-owned structure rather than a multi-operator JV.

Emerging players

• Boldyn Networks (formerly BAI Communications): Neutral-host infrastructure provider specializing in shared connectivity solutions for transit, venues, and 5G networks. Comparable to MBNL in its shared-infrastructure ethos and growing Infrastructure-as-a-Service positioning.

Others

• DigitalBridge Group: Global infrastructure investor focused on data centers, towers, and fiber assets. Comparable as an enabler and capital provider across the mobile infrastructure ecosystem, though not a direct operator competing with MBNL.

Direct peers

• Cornerstone Telecommunications Infrastructure Limited (CTIL): UK joint venture originally established between Vodafone UK and O2 (Telefonica) to share mobile network infrastructure. The closest structural and operational analogue to MBNL: a JV between major UK operators managing shared RAN estate.
